W. THQRP ILATING SYSTEM FOR INCLOSED CARS VENT Filed May 10, 1930ATTORNEY Patented Feb. 21, 1933 UNITED STATESv WILLIAM '1'. THORP, OFHILLSBORO, ILLINOIS VENTILATING SYSTEM FOR INCLOSED CARS Applicationfiled Kay 10,

This invention relates to means for ventilating closed vehicles, anobjectbeing to provide means for supplying air to the interior ofautomobiles, busses, cars and other closed vehicles in a manner toeliminate direct draft andto prevent the entrance of rain or snow.

Another object of the invention is the provision of means for supplyingair to the interior of closed'vehicles for the purpose of ventilation,both when the vehicle is standing and in motion, and for regulating theair supply.

' Another object of the invention is the provision of means forfiltering the admitted air, so that the occupants of the vehicle will beprotected from dust, dirt and other impurities in the atmosphere.

A further object of the invention is the provision of a "entilator,which, in addition to the above and other advantageous features, may bereadily installed for use.

' With the above and other objects in view, the invention furtherincludes the following novel features and details ofconstruction, to beherein-after more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings Figure l is an enlarged fragmentary vertical sectionalview through a ventilator constructed in accordance with the invention.

Figure 2 is a fragmentary elevation looking at the inner end of theventilator as shown in Figure l.

Figure 3 is a similar view with the inner section of the frame or casingremoved.

Figure 4 is an elevation looking at the inner end of the frame or casingwith the adjustable damper plate removed Figure 5 is a side elevationthereof.

Referring .to the drawings in detailwherein like characters of referencedenote corresponding parts, the ventilator constituting the presentinvention is adapted to be applied to an automobile body A.

This ventilator comprises a frame or housing 33 which extends throughthe opening provided in the body A of the automobile and accommodates aframe 34. This frame 34 1930. Serial No. 451,369.

carries a screen 35 and a filtering element 36.

The inner opened end of the frame or housing 33 is closed by a removablecap 48 and this cap is provided with openings 49. The cap 48 is alsoprovided in its flange with bayonet slots 52 which accommodate pins 40extending from the frame or housing 33 adapted to engage any one of anumber of spaced openings 45 provided in the cap 48. If desired theventilator may be provided with a suction fan 46 which is driven from amotor 47 mounted within the cap 48. Passage of air through theventilator arranged as shown in Figure 1 is regulated by the damperplate 41 and the speed of operation of the fan, the damper plate beingadj ustably held in position by means of the spring pressed plunger 44which engages within spaced openings 45 provided in the cap 48.

A motor 47 is mounted upon legs 55 and receives current through aconductor cable 56 which is plugged into a socket 57 carried by theframe or casing 33. This socket has connected thereto a conductor cable.58 by means of which current may be supplied from the battery of theautomobile.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention what is claimed is 1. In a ventilator forclosed vehicles, a cylindrical casing adapted to be positioned Within anopening provided in the body of the vehicle and open at opposite ends, ascreen fitted within the outermost end of said casing, a cap telescopedupon the in nermost end of said casing and having vent 2 meat openings,said ca having peripheral bayonet-shaped slots, ugs on the casing andre- 7 oeived in said slots for detachably loc the cap upon the casing, ashutter piv 5 to the cap to regulate vent openings therein,

and a latch carried by the shutter and en- 7 En ble at selective intswith the cap to o d the shutter in 1 'usted position. '2. In aventilator 201', closed vehicles, a cylindrical casing adapted to bepositioned within an opening provided the bod of the vehicle and open atopposite en a screen fitted within the outermostend of said casing, acap telescoped upon the innermost 15 end .of said casing and having ventopenings, said cap having peripheral bayonet-shaped slots, lugs on theand received in said slots for detachably 10c ing the cap upon thecasing, a shutter pivoted to the cap to regulate vent openings therein,a latch carried by the shutter and engageable at selective points withthe cap to hold the shutter in ad usted position, and a motor operatedfan interiorly of the casing between the cap and said screen. 25 Intestimony whereof I aflix my signature.
